MOBILITY MEASURES FOR THE RESPONSIBILITY CUT

No 2311, Working Papers from Waseda University, Faculty of Political Science and Economics

Abstract: We explore measures of relative social mobility in terms of equality of opportunity. This study aligns with the principles of responsibility–sensitive egalitarianism, distinguishing between responsibility and non-responsibility factors. We introduce an additive decomposability property when these factors are distinguishable and independent. We subsequently provide axiomatic characterizations of mobility indices that evaluate doubly stochastic transition matrices In addition to the conditions for the index values to be the same, we employ the postulate that equalization of life chances is desirable. Moreover, we demonstrate incompatibility in the invariance properties of dimensional changes; that is, the values of the indices cannot be constant according to the number of social ranking categories. Thus, two corresponding compromised measures are proposed
